Manuale_LUA

d, i

Print an int as a signed decimal number. '%d' and '%i' are synonymous for output, but are different when used with scanf() for input.

u

Print decimal unsigned int

f, F

Print a double in normal (fixed-point) notation. 'f' and 'F' only differs in how the strings for an infinite number or NaN are printed ('inf', 'infinity' and 'nan' for 'f', 'INF', 'INFINITY' and 'NAN' for 'F').

e, E

Print a double value in standard form ([-]d.ddd e[+/-]ddd).An E conversion uses the letter E (rather than e) to introduce the exponent. The exponent always contains at least two digits; if the value is zero, the exponent is 00.

g, G

Print a double in either normal or exponential notation, whichever is more appropriate for its magnitude. 'g' uses lower-case letters, 'G' uses upper-case letters. This type differs slightly from fixed-point notation in that insignificant zeroes to the right of the decimal point are not included. Also, the decimal point is not included on whole numbers.

x, X

Print an unsigned int as a hexadecimal number. 'x' uses lower-case letters and 'X' uses upper-case.

o

Print an unsigned int in octal.

s

Print a character string.

c

Print a char (character).

p

Print a void * (pointer to void) in an implementation-defined format.

n

Print nothing, but write number of characters successfully written so far into an integer pointer parameter.

%

Print a literal '%' character (this type doesn't accept any flags, width, precision or length).
